Thanks a lot. Today and tomorrow are holidays in Switzerland, but I'll do it Tuesday first thing in the morning...please have a look at it and confirm. Where do you want me to place a reference?We are currently processing the information that you gave us and I will get back to you in the middle of next week. If there are other Spanish language study materials we are always happy to get them.On the way back I visited a private beach resort. I just wanted to see whether I could get in and it was not a problem at all. The resort belonged to some club on the main land near Cancun.
